Eni Arnica 68

A low-zinc ISO VG 68 hydraulic oil for high-pressure systems

Eni Arnica 68 is an anti-wear hydraulic oil for modern industrial and mobile hydraulic systems running at high pressure. It is built on carefully selected base oils with low-zinc additive technology, which gives good thermal stability and resistance to oxidation and ageing.

With a viscosity index of 148 the oil copes with cold starts as well as high operating temperatures, so it is a sound choice for marine use and for industrial machines that are sensitive to temperature swings.

Where it fits

• High-pressure hydraulic circuits, outdoors (marine, mobile equipment) or indoors
• Systems with fine filtration down to 3 microns
• Installations where temperatures vary widely

Properties

• Protects pumps and components against wear, with long oxidation life for extended drain intervals
• Releases air quickly, which limits cavitation and aeration, and separates water and foam well
• Compatible with the metals normally found in hydraulic systems
• Clear appearance, density 883 kg/m³ at 15 °C, 68.0 mm²/s at 40 °C
• Flash point (COC) 222 °C, pour point -33 °C, demulsibility 15 min at 54 °C, cleanliness ISO 4406 19/17/15

Choosing the right oil

Use this grade where the system builder asks for ISO VG 68 HV hydraulic oil. Check the exact approval in the machine manual and flush or drain thoroughly before a changeover.
